- Tater tots: Frozen tater tots stay crispier during baking and hold their shape better than fresh potatoes. They're the star of this baked breakfast dish.

- Bell peppers: Diced bell peppers (shishito peppers work great too) add sweetness and color. They soften as they cook with the meat.

- Green onions: Chopped green onions bring a fresh, mild onion flavor that brightens each bite.
- Eggs: Whisked eggs bind everything together and create a custardy texture that holds the Tater Tot Breakfast Casserole .

- Kosher salt: Salt seasons every layer and brings out the natural flavors of the meat, vegetables, and eggs.
How to Make Tater Tot Breakfast Casserole
Preheat oven: Set your oven to 375°F and move the oven rack to the top position. This helps the tater tots brown evenly and get crispy on top.
Cook bacon and onions: In your heavy-bottomed, oven-safe pan, sauté the bacon pieces, diced onion, and ½ teaspoon salt over medium-high heat for about 7 minutes. The bacon should render its fat and the onion should turn soft and golden.
Add sausage and peppers: Stir in the cubed sausage, diced bell peppers, and the remaining ½ teaspoon salt. Cook for another 3 minutes, stirring occasionally, until the sausage is browned and the peppers have softened.

Prepare egg mixture: In a mixing bowl, whisk together the eggs with 1 ½ teaspoon salt until well combined. Add the milk and whisk until the mixture is smooth and slightly frothy. Set it aside while you layer the pan.
Layer cheese: Sprinkle 1 cup of mozzarella evenly over the cooked meat and vegetables in the pan. This creates a melty base layer.
Add tater tots: Arrange the frozen tater tots in a circular pattern to fill the pan completely. Pack them snugly but don't overlap them too much.
Pour egg mixture: Pour the whisked egg and milk mixture evenly over the tater tots, letting it settle into the gaps. Sprinkle ½ cup of the chopped green onions on top.
Bake first phase: Place the pan on the top oven rack and bake uncovered for 20 to 25 minutes. The eggs should set and the tots should start to turn golden.

Add final toppings: Remove the pan from the oven and sprinkle the remaining 1 cup of mozzarella cheese over the top. Add the sliced jalapeños if you're using them. Return to the oven and bake for another 5 minutes until the cheese is bubbly and melted.
Finish and serve: Take the pan out of the oven and sprinkle the remaining ¼ cup of green onions over the top. Let the Tater Tot Breakfast Casserole rest for 5 minutes before slicing. Serve warm with a side salad or a drizzle of hot sauce.
Substitutions and Variations
Cheese: Swap mozzarella for sharp cheddar, Monterey Jack, or a Mexican blend. Pepper jack adds extra heat.
Meat: Use crumbled breakfast sausage, diced ham, or cooked ground beef instead of patties and bacon. Turkey sausage works too.
Vegetables: Add mushrooms, spinach, tomatoes, or diced zucchini. Just make sure to cook them first to remove excess moisture.
Spice level: Skip the jalapeños for a milder version, or add a dash of cayenne or red pepper flakes to the egg mixture.
Dairy-free: Use unsweetened almond milk or oat milk in place of whole milk and skip the cheese, or use a dairy-free cheese alternative.
Equipment For Tater Tot Breakfast Casserole
Oven-safe heavy-bottomed pan: A 3.5-quart pan like a 12-inch Le Creuset works perfectly and goes from stovetop to oven without any transfers.
Wire rack: Useful for cooling if you're not serving immediately.
Mixing bowl: For whisking the eggs and milk together.
Whisk: Helps combine the eggs and milk into a smooth mixture.
Measuring cups and spoons: For accurate ingredient portions.
Storage and Make-Ahead Tips
Leftovers keep well in an airtight container in the fridge for up to 4 days. Reheat individual portions in the oven at 300°F for about 10 minutes to keep the tater tots from getting soggy. You can also microwave them, but the texture won't be quite as crispy.
For make-ahead mornings, cook the bacon, sausage, and vegetables the night before and store them in the fridge. In the morning, just layer everything in the pan, pour the egg mixture, and bake. You'll save yourself about 15 minutes of prep time when you're still half asleep.
You can also assemble the entire Tater Tot Breakfast Casserole (except for the final cheese topping), cover it tightly, and refrigerate overnight. In the morning, let it sit at room temperature for 10 minutes, then bake as directed.
